A few questions/suggestions:

./tools/testing/kunit/kunit.py run --raw_output (older versions of
the KUnit parser may not work well if the kernel log is decorated,
e.g. with timestamps, etc — this should be largely fixed for 5.7).
--raw_output is really helpful.
The root cause of missing tests is that tempdir doesn't exist.
I create that file and kunit runs well now. :-P
